The verdict in three sentences
For a Berlin fibre installation contractor running 50 technicians, the best software in 2026 is the one that gets completion evidence accepted by the network operator on the first submission. Below roughly 600 connections a month, a well configured field service SaaS is the fastest win; above 1,000 connections across several wholesale clients, custom software wired into operator portals and the network inventory usually wins over three years. Whatever you choose, GDPR compliant location tracking and a works council agreement are not optional in Germany.
What a German FTTH contractor actually needs to track
Fibre rollout in Berlin is driven by large operators and wholesale programmes, with subcontractors paid per completed unit: building entry, riser work, splicing, measurement and the final home connection. Each step needs photo evidence, OTDR or power meter results and a structured completion report. Missing one item delays payment by weeks.
| Requirement | Typical Berlin volume (2026 estimate) | What the software must do |
|---|---|---|
| Connections per month | 600 to 2,000 | Batch scheduling by street block and crew |
| Photos per connection | 8 to 20 | Guided capture, mandatory fields, offline sync |
| Measurement files | 1 to 3 per unit | Upload and link to the right fibre and port |
| Network inventory updates | Every completed unit | Export or API towards the operator's inventory system |
| Technicians | 50, including 10 to 15 subcontracted | Role based access, multilingual mobile app |
| First visit failure rate | 10 to 25 % | Standard reason codes, fast rebooking |
Berlin crews are often multilingual, so an app that runs in German, English, Polish or Turkish removes a surprising amount of friction on site.
The 2026 ranking of options
We rank types of solutions, not named vendors or agencies. Figures are 2026 market ballparks in EUR, excluding VAT.
| Rank | Type of solution | Upfront cost | Running cost | Rollout time | Data portability | Best for |
|---|---|---|---|---|---|---|
| 1 | Custom field app integrated with operator portals and inventory | 50,000 to 140,000 EUR | Maintenance 500 to 1,800 EUR a month | 4 to 7 months | Full if code and data are handed over | Over 1,000 connections a month, several operators |
| 2 | Telecom specialised field SaaS | Setup 4,000 to 15,000 EUR | 45 to 75 EUR per technician a month | 1 to 3 months | Medium, photo export often limited | 500 to 1,200 connections, standard process |
| 3 | Generic field service SaaS | Setup 1,500 to 6,000 EUR | 30 to 50 EUR per technician a month | 1 to 2 months | Medium | Under 600 connections, one client |
| 4 | Open source ERP with field service module (Odoo type) | 12,000 to 40,000 EUR integration | Hosting or subscription, public price varies by plan | 2 to 5 months | Good | Firms wanting payroll and accounting in one stack |
| 5 | Spreadsheets and messaging apps | Near zero | Heavy admin time | Immediate | Full | Under 100 connections, short transition only |
Over three years with 50 technicians, a specialised SaaS at 60 EUR a head costs about 108,000 EUR in subscriptions before setup. A custom build at 80,000 EUR with 1,100 EUR monthly maintenance comes to about 119,600 EUR, but removes double entry into operator portals and leaves you owning the asset.
Where Kolonell fits
Kolonell is one nearshore option for the custom route. Kolonell's prices for custom applications are 6,100 to 10,670 EUR for a medium complexity app (4,000,000 to 7,000,000 FCFA) and 10,670 to 22,870 EUR and above for a complex one (7,000,000 to 15,000,000 FCFA and above), with maintenance at 53, 114 or 183 EUR a month. A scoping workshop tells you whether your volume justifies custom work or a configured SaaS.
Criteria that separate good from risky
| Criterion | Question to ask | Red flag |
|---|---|---|
| Evidence quality | Are photos timestamped, geotagged and validated before submission? | Checks happen only back at the office |
| Offline mode | Does the app work a full shift without signal in basements? | "You need a connection to close the job" |
| GDPR and works council | Can tracking be limited to working hours with a documented purpose? | Continuous tracking, no retention policy |
| Operator exports | Are completion reports produced in each operator's required format? | Manual copy and paste into portals |
| Exit terms | Can you export all history, photos included, at no cost? | Paid or partial exports |
| Support | Who answers at 6.30 am in German? | Ticket only support in another time zone |

Kolonell builds websites that attract clients, optimized for the Sénégalese market. Free quote in 2 minutes.
Illustrative example, fictional firm: Markus, managing director of a fibre contractor in Berlin, 50 technicians, 1,200 connections a month for two operators. His rejection rate is 14 %, so 168 files a month need rework, around 90 of them with a second visit at 95 EUR full cost: 8,550 EUR a month lost.
With an app that blocks job closure until mandatory photos and measurements are attached, he targets 5 %: 60 files and about 30 revisits, 2,850 EUR a month. The 5,700 EUR monthly saving, plus two admin days a week freed, pays back an 80,000 EUR custom build in about 14 months.
FAQ
What should a Berlin fibre contractor budget for field software in 2026?
Plan 30 to 75 EUR per technician a month for SaaS, so 18,000 to 45,000 EUR a year for 50 technicians. Custom software typically runs 50,000 to 140,000 EUR depending on operator and inventory integrations (2026 market ballpark).
Do we need works council approval for technician tracking?
In Germany, technical systems able to monitor employee performance generally require works council involvement where one exists, and GDPR requires a documented purpose and retention limit. Plan 4 to 8 weeks for that agreement in your rollout timeline.
How long does a switch take?
A SaaS rollout takes 1 to 3 months including crew onboarding. A custom tool takes 4 to 7 months, with a pilot on 5 to 10 technicians before full cutover.
Should invoicing live in the same tool?
Above 500 connections a month, yes: matching approved units to invoices typically recovers 2 to 4 % of work that was never billed. A connector to your existing accounting software is often enough.
Can we get our photos back if we leave a SaaS?
Only if the contract says so: require a full export, photos included, within 30 days at no charge. Without that clause, hundreds of thousands of images can stay locked in.
